Um, not me. I'm exercising for me: to be healthy, to be happy, to be strong.
That strong portion has some body role models (drumroll please):
Sigourney Weaver in "Aliens." What a woman. What a character.

Tough, strong, and aging beautifully.
Linda Hamilton in "Terminator 2." While I think her body fat was lower than I want to go, I admire her determination a great deal. She had to work hard for that physicality.

Delts, biceps, and triceps - the trifecta of perfection.
Is it just me, or are our modern day action stars a little ... anemic? Linda and Sigourney are authentic, and I have not seen their like in many a year.
Celebrities - Jada Pinkett and Madonna. Showing that world that you can still find physical improvement with age, you do not have to live with decline, that is a choice.

Those legs have a been her lifelong quest.
Athletes - The Williams' sisters and Joan Benoit and, well, all marathoners (and ultramarathoners). I admire the drive marathoners need to possess in order to cross that finish line. It doesn't hurt that they pretty much all have great legs.

Ladies, I admire your determination and your skills. When I want to skip a lift day or the long run, I think of you all - and drag myself off to the appropriate room. Thanks for the inspiration.
